01
Brief and responsibilities
The brief was to create music-promotion videos featuring IP characters. I refined an existing workflow, focusing on prompts, storyboards, and generated outputs.
The main issues were character consistency across shots and matching visual cuts to the music.
02
Plan cuts around musical beats
I added instructions to analyze BPM and rhythmic patterns, using strong beats as a basis for shot changes.
These instructions guide generation; the resulting audio and visuals still need review.
03
Create character storyboards first
The workflow first generates storyboard images containing the IP character, then uses them to generate video.
This gives video generation a concrete visual reference to support character consistency.
04
Translate references into prompts
In response to timing feedback, I studied camera and editing choices in K-pop music videos from the preceding five years, organizing examples into the system prompt.
The team handed outputs to backend developers for deployment. My contribution was prompt and content refinement within the existing workflow.
I organized music-video visual references into seven scene prompts, specifying composition, space, palette, lighting, and unwanted elements. The original English text is preserved below; artist names serve as style labels.
Make visual choices explicit
For example, the TWICE entry places furniture at the edges, keeps the center clear, and names a pastel palette. STRAY KIDS specifies an eye-level, horizontal composition with a debris-free center. NEWJEANS separates composition, lighting, camera settings, textures, and negative prompts.
These excerpts illustrate scene-design constraints. Requirements vary by style: the ATEEZ entry retains dust and debris to create an abandoned setting.
TWICE · Bright popView original prompt

NEWJEANS · Retro urbanView original prompt
[Composition/Location] Wide-angle eye-level shot looking toward an urban railroad crossing in a densely populated East Asian city. In the mid-ground, a white and yellow commuter train is blurred as it speeds across the frame horizontally. The foreground features a gray asphalt road with distinct yellow double lines. Overhead, two massive yellow industrial steel truss structures with "4.2M" height limit signs and electronic traffic signals span the road. Background shows high-rise residential apartment buildings with visible air conditioning units and a lush green hillside in the far distance. [Lighting Logic] Bright, high-contrast natural daylight. The scene is illuminated by direct overhead sun, creating sharp, short shadows. The light reflects off the metallic surfaces of the train and the industrial yellow trusses, giving the entire environment a clean, slightly overexposed urban summer vibe. [Camera Parameters] Shot on a high-end digital cinema camera, 24mm wide-angle lens, f/5.6 aperture for deep depth of field. A fast shutter speed is used for the static elements, while the train in the mid-ground has a slight motion blur to convey speed. High dynamic range (HDR), 8k resolution. [Style & Texture] Modern urban aesthetic, J-pop or K-pop music video set style. Textures include gritty asphalt, weathered concrete buildings, smooth metallic train surfaces, and industrial matte yellow paint on the steel trusses. The color palette is dominated by "caution yellow," asphalt gray, and clear sky blue, creating a vibrant, high-energy atmosphere. [Negative Prompt] (Negative Prompt): human, people, girl, woman, dancers, face, body, movement, crowd, blurred figures, person in uniform, text, watermark, signature, messy, dark, indoor, night shot, low resolution, distorted perspective.
